Ive got an rb30 turbo with a really quiet exhaust. The car seems to drive perfectly, run really smoothly. Are you saying It could just pre ignite at any time or be detonating and i wouldnt even hear it? I thought pre ignition sounded like a marble or something in your cylinder, like a really pronounced bang?
Also what is the optimal spark plug to run in it. Its a standard N/a motor, high comp, n/a cam etc, with vlt injectors, vlt computer, stock manifold turbo etc. Will be installing water injection soon and trying to push it to 14psi. From what ive read if i get the water right i can lean it out a bit even on the n/a high comp motor. Only problem with doing that is if the water fails then almost certainly your motor will too. Its been going for 2000km and the sparkplugs have no signs of wear, this is a good sign of no detonation right?
And in your opinion how much longer (i,e a few seconds?) can forgies handle pre ignition for versus cast pistons?
Kind regards,
Jason.
